Fas和c-myc蛋白胞浆内阳性，在骨肉瘤的高分化细胞(骨母细胞型和软骨细胞型瘤细胞)和骨化性纤维瘤、骨纤维结构不良、骨痂组织中骨母细胞呈强表达；而在低分化瘤细胞和纤维母细胞则呈弱表达。

To be qualified as an EOS, the tumor must (1) arise in the soft tissue and not be attached to bone or periosteum,(2) have a uniform sarcomatous pattern ( to exclude the possibility of a mixed malignant mesenchymal tumor),(3) produce osteoid and/or cartilage matrix.

本病的诊断标准是(1)发生于软组织而与骨及骨膜部不相连；(2)具有一致的骨肉瘤表象，以排除混合性恶性间叶组织肿瘤；(3)可产生骨质或软骨样基质。
